Measurement of Hydroquinone

Benzene-free synthesis of hydroquinone.

All current routes for the synthesis of hydroquinone utilize benzene as the starting material. An alternate route to hydroquinone has now been elaborated from glucose. While benzene is a volatile carcinogen derived from nonrenewable fossil fuel feedstocks, glucose is nonvolatile, nontoxic, and derived from renewable plant polysacharrides. Glucose is first converted into quinic acid using microb...

Benzoquinone-Hydroquinone Couple for Flow Battery

At present, there is an ongoing search for approaches toward the storage of energy from intermittent renewable sources like wind and solar. Flow batteries have gained attention due to their potential viability for inexpensive storage of large amounts of energy. While the quinone/hydroquinone redox couple is a widely studied redox pair, its application in energy storage has not been widely explo...

Hydroquinone detection by BN nanotube: DFT studies

Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward hydroquinone (C6H4(OH)2) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G(d) level, and it was found that the adsorption energy (Ead) of hydroquinone on the pristine nanotube is  a bout -7.77kcal/mol. But when nanotubes have been doped with Si and Al atomes, the adsorption energy of hy...

THE BIOLOGICAL ACTIVITY OF wTOCOPHERYL- HYDROQUINONE

The functional r81e of a-tocopherol in the animal body is not understood. It may act specifically through some enzyme system and perhaps also in a non-specific manner as a physiological antioxidant (1). Its action has been related to the existence of an oxidation-reduction system, but the postulation that tocopherylquinone takes part in that system could not be confirmed, because this compound ...
